Hmmh, that's unexpected...
Where did you read that?
It's in the download filename ..
So my thought was basically.. either it was forgotten to change the filename .. or the link was going to the beta and noone ever got to play the "final" :)
Indeed... well seen !
In fact it's a "bug" in itch.io
The download module automatically renames the zip with the initial name of the channel (which was... beta at the beginning).
My original zip is correct. I don't know if I can change it... I did not find how to do it
In any case it's the correct (final) version that you downloaded
